Commit 01ca4010 (libvirt v5.1.0) moved address reservation for hotplugged interface devices up to an earlier point in qemuDomainAttachNetDevice(), because that function calls qemuDomainSupportsNicdev() (in the case of VIR_DOMAIN_NET_TYPE_VHOSTUSER), and qemuDomainSupportsNicdev() needs to know the address type (for ARM machinetypes) and returns incorrect results when the address type is "none". This bugfix unfortunately caused a regression, because it also made PCI address reservation happen before we noticed that the device was a *hostdev* interface. Those interfaces are hotplugged by just calling out to qemuDomainAttachHostdevDevice() - that function would then also attempt to reserve the *same PCI address* that had just been reserved in qemuDomainAttachNetDevice(). The solution is to move the bit of code that short-circuits out to virDomainHostdevAttach() up *even earlier* so that no PCI address has been allocated by the time it's called. https://bugzilla.redhat.com/show_bug.cgi?id=1744523Signed-off-by: NLaine Stump <laine@redhat.com> Reviewed-by: NAndrea Bolognani <abologna@redhat.com>
